I am attempting to limit the travel of most school buses down local streets and other undesired locations without creating barriers. We cannot fully limit travel due to special education buses needing to be able to traverse down the streets should there be student there. I am accomplishing this using network parameters and attributes. I am able to adjust the parameter in the layer properties during a solve at the desktop level. Is there a way during a Python script so that I can make those adjustments and run repeated solves for a fleet or am I stuck doing one at a time and adjusting it manually?
